If faster AF is possible with the existing lenses, that would be nice. But if not, I'm OK with the current level of auto focus. And as long as there's either a physical or virtual distance scale somewhere on the camera, zone focus can work when the AF isn't fast enough. So I'm cool with it. Other than that, I'm sure the sensors will continue to get better and while the current sensors are more than adequate for my needs, better is always better, even when the returns are diminishing. I'm not really interested in any additional whiz-bangery for the X-Pro - I quite like its simplicity and straight-forward approach. I have an OMD for when I want FEATURES and cool stuff. The X-Pro is just an awesomely straight-forward camera. So other than a weak wish for better AF, my greatest hope is just that they don't screw up a good thing by "improving" it in the wrong direction. Its a pretty effing wonderful camera just as it is, with some damn fine lenses...

Couldn't have said it better no matter how hard I tried.
